Pop!_OS is presently based on gnome a broken mish mash of c and JavaScript and extensions which rather than being written to an actual extension API merely monkey patches the JavaScript.
When the underlying JavaScript to be patched created by gnome changes extensions can silently break.
Outside of gnome land this really isn't at all normal. One could for example have used i3wm without issue for the last 12 years, awesomewm for 14, compiz for 16, KDE for 25 years and if you really hate change there is a fork of KDE 3 so you could have pretended its still 2002 for the last 20 years if you like while still actually making use of current versions of everything from the kernel to your web browser.
